Hello,
I have a doubt regarding "the measure" of the truss rod. I had learned (I even have the book by John Carruthers) that, setting a capo on the first fret and pressing down the string where the neck joins the body, the string heigh at around the 7th fret should be 0.15 for bass and 0.10 for guitar.
Today, I took my Yamaha BBP34 from my luthier and it plays like a dream. When I took it, his assistant told me that the adjustment was horrible. I agreed that he could adjust it. I measured and the strings heigh is around 1.5 mm each string (1/16") and the truss road (measured with the capo) is at 0.10". The assistant is a guitarist, but I cannot say anything bad. My Yamaha plays now incredibly well and it does not have any fret buzz. Do you think I should keep it like that or it may create a problem?
